Simple but working.
Their isn't much to say about this.
So far it's pretty good. I really don't need to mention anatomy or form or anything about the basics. This is a very good sign.
The things you do need to work on is the Background which is kind of bland and boring and you need to shade the character. At the moment the character is more flat than a piece of wood in a sandpaper factory.
That little bit of depth could reall help this out.
Also I notice that the lines are rather pixelated. IF this was down in Ms Paint then you might want to switch over to Photoshop or Gimp.
